My conception led to a shotgun wedding. Two years in my sister came along. Divorced two years after that. Dad was incarcerated not long after that so it was easy to view him as the bad guy.
As far as shaping my view on marriage, it leads me to be cautious about who I bring life into this world with. While I get that there's more to life than my parents' experience or world, view, I still keep it in mind.
